-LRB- CNN -RRB- It 's a case of mistaken identity that reached international proportions .

A 14-year-old girl was returned to Mexico from Texas on Wednesday after DNA tests showed she 's not related to a woman who claimed the teenager was her daughter .

Mexican federal police seized Alondra Luna Nuñez on Friday in the colonial city of Guanajuato , in central Mexico , believing she was the daughter of a Mexican national living in Houston .

Several videos show the moment the girl was taken out of her middle school . In the footage , Alondra appears terrified , screaming at the top of her lungs and desperately trying to free herself from officers who are dragging her out of the building .

After a struggle that lasted several minutes , the 14-year-old was put inside a federal police truck that sped away as witnesses , including the teenager 's aunt , watched and recorded .

According to Mexican authorities , the woman in Houston claimed in a 2007 petition that her daughter had been illegally taken to Mexico by her biological father without her consent .

According to a statement from the Mexican Foreign Ministry , the woman had recently traveled to Guanajuato and seen her daughter there .

`` Derived on this information ... and in compliance with international law ... the judge in charge of the case asked Interpol to intervene to make the girl appear at a hearing in which the court would confirm her identity , '' the statement said .

But what happened next puzzled both Alondra 's family and Mexican public opinion : The teenager was sent to the United States before her identify was positively confirmed .

Once in Houston , and with questions about her identity being raised by the girl 's biological parents , the Mexican Consulate in that city ordered DNA testing . The results confirmed that Alondra is not the daughter of the Houston woman .

`` I will have my girl at home . We hope she 's OK . We are taking action on the matter , '' Alondra 's mother -- Susana Nuñez -- told Milenio Television . `` They stole my child . ''
